Ok. I admit to being somewhat of a snob when it comes to the speed of the lenses I use. The list of my f/2.8’s includes the 120-300mm, 70-200mm, 24-70mm, 150mm Macro & 105mm Macro and a 15mm fisheye. For f/1.4 the list is all primes with the 85mm, the 50mm and the new 35mm Art lens. All of these speed demons are from Sigma of course.

So along comes the latest member of their new Global Vision lenses; the 24-105mm at what I thought was a not-so-speedy f/4.0…

I really need to have a talk with myself about it. Here’s a transcript of that conversation:

Speedball Me: “Hey, hey! Look at this! A 24 to 105 Art lens from Sigma, sweet! Wait a minute… It’s only an f/4.0? Really?!? What’s up with that?”

Photo Me: “Ah, come on Speedball, it’s only one stop slower. That’s no big deal to get the extra reach. I’ll take 105mm at f/4.0 over 70mm and f/2.8 any day. Really!”

On my next shoot I found myself once again using this versatile light bending tool. I had a brightly backlit set with sheer curtains for Vanessa Guillemette pose with. This situation was ripe for creating lens flare. Yet there isn’t any at all.

Excellent. May I as a question or two. What make body are you using and have you ever played with the 70_200 f2.8 and your opinion will be appreciated. I want to add it to my 70-300 Apo, 17-70f2.8 and 105 f2.8 macro. I will perhaps add a 1.4 converter to it.
